Free Quilt Block Pattern
The Propeller quilt block can be used as a starter block for beginner quilters, because it contains only simple shapes -- the square and the most commonly used shape (other than the square) -- the half square triangle.
For those who like easy math, this quilt block is designed as a 10" block rather then the more commonly used 12" blocks. However, I have included measurements for a 7 1/2" block as well as a smaller 5" block, so you have your choice. The quilt block is constructed as an uneven nine patch as all rows are not identical in size.
